Pressure compensation device

Abstract

Pressure compensators ( 1 ) for stabilizing a flow of water are disclosed. The pressure compensator ( 1 ) includes water compensating channels ( 3 ) formed on the outer periphery of their body ( 2 ), and flow orifices ( 4 ) passing through the pressure compensator ( 1 ), so that the water compensating channels and the flow orifices control the flow rate of the water at varying pressures. The body of the pressure compensator ( 1 ) preferably comprises a flexible material, such as rubber.

The invention claimed is: 
     
       1. A pressure compensator for stabilizing a flow of water comprising a pressure compensator body comprising a flexible material and including an upper portion including an upper surface having a conical shape, a lower portion including a lower surface having a cylindrical shape, and an outer periphery, a plurality of concave water compensating channels formed in said outer periphery of said pressure compensator body, and a plurality of flow orifices passing through said pressure compensator body from said upper surface to said lower surface thereof, whereby the shape of said plurality of concave water compensating channels and said plurality of flow orifices is altered so as to control the flow rate of said water in said pressure compensator body at various water pressures. 
     
     
       2. The pressure compensator of  claim 1  wherein said pressure compensator body includes a plurality of columns disposed on said lower surface of said pressure compensator body for interacting with said plurality of concave water compensating channels and said plurality of flow orifices to control the flow rate of said water in said pressure compensating body at various water pressures. 
     
     
       3. The pressure compensator body of  claim 1  wherein said flexible material comprises rubber. 
     
     
       4. The pressure compensator body of  claim 3  wherein said rubber comprises nitrile butadiene rubber. 
     
     
       5. The pressure compensator of  claim 1  wherein said pressure compensator body is in the shape of quincunx. 
     
     
       6. The pressure compensator of  claim 5  wherein said concave water compensating channels are evenly distributed around the outer periphery of said pressure compensator body. 
     
     
       7. The pressure compensator of  claim 1  wherein said plurality of flow orifices are disposed in said upper surface of said upper portion having said conical shape. 
     
     
       8. The pressure compensator body of  claim 1  having a height of less than about 10 mm. 
     
     
       9. The pressure compensator body of  claim 1  having a width of less than about 12 mm.
